Julia,

 

It is not clear from your picture if there is some protection under the plastic sheet, to protect the milling bed and the milling bit. If not, is it not necessary? I always use a scrap piece of ply but I would happily not use it as it doesn't help much when I try to align the part I want to mill.

You need something if you’re cutting right through. I think I can see the edge of a sacrificial piece of something at the extreme right hand edge of the picture where the step clamp is visible also.

As a rule it is wise to have a sheet of something under the job.  Ply,  aluminium,  MDF, Tufnol etc.  This can be bolted or clamped to the bed without the clamps interfering with the cutting. Double sided tape is very useful for holding the sheet being cut onto this. For metal I use the Diall stuff and use a hair dryer to get it unstuck afterwards. Maybe something less grippy for plastic but I have not done much of that.

.... One thing I have fund is really useful when cutting thin sheet material is 3M re-positional spray mount. Its great at holding material down while cutting.

 

 

The adhesive can be easily dissolved using IPA when finished.

 

Julia :)

Good to see you posting again , Julia.  There are tips here that don't only apply to 2mm model lers. Since you stopped writing your own blog, I've often wondered what you did with Highclere.

I will start off by adding this...

I recently ordered a countersink tool from APT tools which was added onto an existing order. I have always struggled to de-burr really small holes as most countersinks cannot cut small holes. This countersink looks like it will cut right down to the point. Available in 90 deg and more traditional 60 deg angles.

 

[...]

 

This is an amazing tool - I didn't even know such things exist, soooo much better than an oversized drill bit. I purchased one, not from APT but from Drill Service (Horley) and I tested it on some scrap brass and P/B. I kept using it as it was so satisfying to see how well the BA12 bolts "sunk" into the holes :)

 

And there is a countersink tool on each end of the rod!

 

Thanks again, Julia, for bringing this tool to my attention!

Fit that and you will never be constrained to using 1/8" shank dia tools anymore! It makes the machine seriously more flexible when it comes to what and how you cut things.

Julia, will this spindle mod take 0.5mm HSS drill bits with the same size shank?

Hi Valentin.

 

The spindle mod upgrades the milling machine to accept ER11 collets. It will therefore give you the ability to take a wider range of tools.

Plenty of suppliers of ER11 collets as they are pretty standard, ranging from cheap Chinese to high quality precision manufactured types.

That looks great Julia. Do I take it the automated part is the relational rotation of both shafts and tooth cut depth and feed rate are manual? Brilliant whatever, more power to your elbow.....

.... The parts were printed on a FDM machine. It makes producing parts for these mods so easy!

 

I don't follow this thread regularly - all this mechanical 'know-how' is a bit lost on me - but I was interested to see that you use a 3D printer for making some parts.

 

I find 3D printing enables me to build models I couldn't have dreamt of before.  Now, I have started using the printer to make detailed overlays, over brass components.   This approach means that I still have the pleasure of creating robust and well-weighted models.  I call it my 'hybrid' construction method.

 

Happy New Year :)

Thanks Bob.

 

Yes, you are absolutely correct. I didn't want to overcomplicate it by automating anything else other than the rotation. Its not that hard to set the depth etc.

Hi Mike.

 

I am a firm believer in what you say there. Its all about using the right manufacturing method to get the right results. There are far too many people out there who rely on one thing like 3DP to make as much as possible when a different method would produce far better results.

 

Julia :)
